## Overview

CoreCapital is a desktop banking GUI. Users log in or register, then enter a main application with dashboard, card, and user-information pages; the dashboard displays accounts and can create additional accounts. A separate, older banking demo in ContoBancario.py models in-memory deposits and withdrawals. Source excerpts establish the login, registration, account, and navigation wiring; card-page details and some dashboard panels are only evident from their module structure, so their internal behavior is not inferred.

Main entry points: [`database.py`](https://github.com/valerrb/banca---app/blob/main/database.py) (Database access), [`views/login.py`](https://github.com/valerrb/banca---app/blob/main/views/login.py) (Login view), [`views/main_app.py`](https://github.com/valerrb/banca---app/blob/main/views/main_app.py) (Main app router), [`views/signin.py`](https://github.com/valerrb/banca---app/blob/main/views/signin.py) (Registration view)
